SPECIFICATION forming part of Letters Patent No. 462,174, dated October 27, 1891.

Application tiled May 9,1891. Serial No. 392,176. (No model.)

T all whom it may concern.-

Be it known that I, Louis STooKsrEoM, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Vapor-Stoves, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to certain improvements intended more particularly to be used on that class of vapor-stoves wherein gasoline is used as afuel, and which is conveyed from a tank through a vaporizing-chamber, from which the carbureted air is conveyed to a burner, VWhere it is ignited.

My invention consists in features of nov- 1 elty hereinafter fully described, and pointed out in the claims.

` Figure I is a perspective view illustrative of my invention. Fig. II is an enlarged vertical view through one of the nozzles through Which the oil passes from the horizontal into the vertical pipes. Fig. III is an enlarged end View of one of the valve-stem heads, showing also the dial in connection with Which the valve-stem head Works. Fig. IV is a vertical section taken on line IV IV, Fig. III. Fig. V is a view similar to Fig. III, but showing a modification. Fig. VI is a section taken on nue vi vi, Eig. v.

Referring to the drawings, l represents part of the frame of the stove.

2 represents the pipe leading from the oilreservoir, (not shoWn,) which may be provided ivith a valve 3 and which communicates with a horizontal pipe et,-from which the oil passes to the burners of the stove (not shown) through nipples 5 and vertical pipes 6, the nipples fitting loosely in the open upper ends of the pipe 6, so that the pipe a can be removed With the tank when the latter is p to be illed.

with extending fingers l0, as shown in Figs.

I and III. The heads S are made hollow and of conical shape to tit over-similar shaped collars ll on the valve-stems. (See Fig. IV.) The eXtreme ends of the valve-stems are threaded to receive nuts l2, and by tightening these nuts the heads 8 are pressed against the collars Il, and thus the heads S are se curely held on the valve-stems with a means for adjusting them, which is done by simply loosening the nut-s l2 and turning the heads to the proper positions and then tightening the nuts again.

13 represents the dial-plates, in connection With Which the fingers l0 of the valve-stein heads S operate. There is a plate foreach valvestern, and in my preferred construction each plate has a simple notch,as indicated at let, Figs. III and IV, to receive its valve-stem 7 and afford a support for the stem. Each dial-plate has a pin or stop l5, against which the finger l0 impinges when the valve is moved to its open position. One ot' the purposes of this pin is to limit the travel of the finger, and consequently the extent to Which the valve can be opened, and avoids the possibility of the operator turning the valve-stern past the signal Open and on around to the signal Closed, When the iinger would indicate that the valve Was closed, when, in fact, it Would be Wide open. The pin avoids any possibility of such occurrence.

In this class of vapor-stoves the construe Ation is such that the tank, together With the prevents the tank from being removed untilA all of the valves are closed or acts to remind the operator when about to remove the tank that all of the valves are not closed, and to accomplish this I in, my preferred form of construction form a lug or projection 16 on the outer end of each linger 10. This lug lits over the periphery 'of thedial-plate 13, as shown clearly in Fig. III. As the valve stein is turned, the lug Will travel around the periphery of the plate, and it will be understood that as the tank, together with the parts removed with it,has to be lifted in a vertical direction the lug on the lingerwill prevent this removal of the tank except when the valve is turned to its closed position, for not until then Will the lug on the finger leave the peripheryT of the dial-plate as the valve-stem leaves the notch 14. When the valves are turned to their closed posit-ions, the tank, With the other parts, may be readilylifted koff from the stove, and after the tank has been filled the parts are replaced and ready for use. In addition to the function ascribed to the pin 15 it also serves to prevent the tank and other parts being removed When the valves or any one ot' the valves is open for any effort to remove the parts in an upwardly direction. When any one of the fingers would be on the open side of the dial-plates and above a horizontal line drawn through the valve-stem the finger Would impi'nge against its pin 15 and prevent the removal of the parts. The pin 15 is not, however, absolutely essential, for the movement of the valve might be so limited in the open direction that the linger Would not move to a horizontal line drawn through the valve-stem, and then it is obvious that the tank and other parts could not be removed when any one of the valves Were open, even in the absence of the pin l5.

In Figs. V and VI, I have shown a modification Wherein the dial-plate-13 is rigidly and permanently secured to the stem 7, so as to be turned with and by the stem. In this form of the invention the dial-plate has a semicircular flange or rib 17, engaged by a hook 18, secured to the frame l of the stove. In turning the valve to open it the movement is regulated by a projection 19 on the rib 17 coming against the hook 18, and when the valve is closed the end 2O of the rib will .pass out of engagement With the hook 18, and then the parts may be removed to lill the tank.

Under certain circumstances it is of advantage to be able to remove the tank from the stove immediately without being obliged to take t-he time to lirst close all valves, which operation will consume several seconds at least. For instance, a valve may have been opened through error Without lighting the burner to consume the gasoline fed by the valve, or the tank may become leaky and the gasoline finding its Way to the lower part of the stove may accidentally be lit and make a large llame, endangering the contents of the tank and making it advisable to remove the tank With the least possible loss of time. In order to enable the operator to do so With a stove provided With myinvention and yet retain the advantages thereof to a very great @sativa extent` I prefer to construct and arrange the several parts which act to prevent the tank from being removed while a valve is open in such a lnanneithat if the tank is removed with a sudden jerk or more force than is generally applied for that purpose the parts Will yield enough to allow the tank being removed Without first closing the valve. This may be accomplished in quite a number of different u ays, which will readily suggest themselves, by constructing one or more of the parts in such a manner that they Will yield or spring enough to allow them to disengage Whenever a sudden jerk or more force is applied than is generally the case, but not otherwise.

It is obvious that other means than the finger and dial-plate may be employed .Without deviating from the spirit of my invention, which consists in providing the valve-stem with a linger or equivalent device, which linger, by the movement of the valve-stem to which it is attached, is made to engage with another hook or plate attached to an immovable part of the stove Whenever the valve is opened and made to disengage Whenever' the valve is closed.

I claim as my invention- 1. In a vapor-stove, the combination of a stove-frame, a tank, a feed-pipe, and a valve, the tank, feed-pipe, and valve connected together and adapted to be removed together from the stove-frame, a finger and a plate, one attached to the valve and moving with the valve as it is opened, the other attached to the stove-frame, the linger and plate adapted to engage so as to hold the tank, feedppe, and valve to the stove-frame when the valve is opened, and to disengage when the valve is closed, substantially as and for the purpose set forth.

2. In a vapor-stove, the combination of a frame, a tank, a feed-pipe, and a valve, the tank,feedpipe, and valve connected together and adapted to be removed together from the stove-frame, a finger provided with a lug and connected to the valve-stem, and a dial-platev secured to the frame of the stove and adapted to act in connection with the finger to hold the tank, feed-pipe, and valve to the stoveframe When the valve is open and permit the tank, feed-pipe, and valve t-o be removed from the stove-framewhen the valve is closed, substantially as and for the purpose set forth.

3. In a vapor-stove, the combination of a stove-frame, a tank, feed-pipe, and valve connected together and adapted to be removed together from the stove, a finger having a lug, and a dial-plate having a pin 15, substantially as and for the purpose set forth.
